I have two PC’s I want to upgrade to Windows 7. I have run Windows 7 Upgrade Advisor on both PC’s. The results for both is that they could run Windows 7 64 bit. I am shopping for Windows 7 on eBay and need help picking the right version.
I am going to start with an HP Compac nc6400 laptop running XP 32 bit (not sure if XP had a 64 bit version). I got this PC from a business where my son used to work. I would like to take it to 64 bit if I could. One question I have is can I use Windows 7 Upgrade on this PC since it is likely to have an OEM version of XP installed or do I need a Full version. Is there any problem moving it to a 64 bit since it is 32 bit XP now? Is there anything I have to do special to move it to 64 bit?
The other is a Dell Inspiron 530 desktop running Vista Home Premium 32 bit. I am pretty sure undecided whether to move this to Windows 7 64 bit or keep it at 32 bit. What would be your advice? I thought I saw you cannot upgrade 32 bit to 64 bit. Is this true? Can I use a Windows 7 64 bit Upgrade disk but do a clean install and then reinstall programs and restore data? Or do I need a Full version of Windows 7 if I want to get to 64 bit?
I appreciate any advice on how to proceed.
